Details
Manual: AA-AB32321
Overview：
Welcome to use this 2 x 125W Class D audio amplifier board by Sure Electronics.
It integrates high performance IRS2092 supporting dual channel audio amplification.
Both of channels are capable of outputting nominal power simultaneously and continuously.
It’s suitable for amplifier enthusiasts or hobbyists to finish a complete amplifier system.
Resistance and capacity components of high quality, including Metallized Polyester (PET)
Capacitors and lower ESR electrolytic capacitors, high performance inductors are used to
gain the perfect timber, finally realize high S/N ratio, low THD+N, wide frequency response
range etc.
Features:
Specifications typical @ +25℃,Powered by ±50V DC, unless otherwise noted. Specifications
